Introduction

The Compaq StorageWorks SAN Switch 8 is an 8-port Fibre Channel switch

targeted at such applications as Microsoft Windows NT, Unix, OVMS, or

other operating systems connecting three to five servers, storage units, and

tape devices.

Compaq StorageWorks SAN Switch 8

The SAN Switch 8 consists of a motherboard with connections for up to eight

Giga Bit Interface Converter (GBIC) modules, one or two power supplies, a

fan assembly, and a chassis with a serial port and an RJ-45 Ethernet

connection. The switch’s management function lets you monitor frame

throughput, error statistics, fabric topology, fans, cooling, media type, port

status, and a variety of other information to aid in system debugging and

performance analysis.

Compaq StorageWorks SAN Switch 8

Features

The SAN Switch 8 has the following features:

■ Simplicity—The SAN Switch 8 is easy to set up and configure. After

the Power-On Self-Test (POST), just add the switch’s Internet

protocol (IP) address. The remainder of the setup is automated.

■ Intelligence—The operating system allows discovery of all connected

devices and determines optimum data paths without intervention.

■ Flexibility—The GBIC modules support single-mode and multi-mode

fiber transmission media. The switch’s modular construction allows

flexibility in creating, upgrading, maintaining, and configuring a fabric.

■ Reliability—Highly integrated, reliable, multifunction Application

Specific Integrated Circuit (ASIC) devices are used throughout the

switch.

■ High performance—The low-latency, high-performance design

requires no processor data path interaction. The Fibre Channel

bandwidth is 100 MB/s per port (full duplex).

NOTE: The latency can differ when the device or destination is configured in a loop.

■ Automated congestion management—Virtual channels enable the

switch to perform sophisticated congestion management techniques

automatically.

■ Cascading—Switches can be cascaded for large fabric support.

Switches can be interconnected for a large fabric with multiple fabric

connections.

■ Compatibility—The SAN Switch 8 is designed to operate with other

Compaq StorageWorks Fibre Channel Switches using a compatibility

mode.

■ Universal Ports—Switch ports are designed to support F_, FL_, and

E_Port modes of operation. The software automatically selects the

optimum mode of operation.

Part Number: EK-BCP24-IA / 161355-001 File Name: B-CH1 INTRODUCTION.DOC Last Saved On: 9/30/99 10:18 AM

The following table describes the switch’s technical features.

Table 1-2

SAN Switch 8 Technical Features

Feature Description

Login (FC) Explicit fabric login is supported.

Data field size The Fibre Channel frame can be up to 2112 bytes in size. The number

of bytes must be a multiple of 4.

Buffering A total of 128 standard-size receive frame buffers are available for

each set of 4 Fibre Channel ports.

Adjustable

buffer-to-buffer

credit

Buffer-to-buffer credit for each F/FL_Port can be up to 31 credits. For

the E_Port, buffer-to-buffer credit can be a total of 31 credits

distributed among all 8 virtual channels.

In-order frame

delivery The switch delivers the frames to a destination F/FL_Port in the same

order received by the source F/FL_Port. The in-order frame delivery is

maintained within a fabric of multiple interconnected switches.

Automatic

address

assignment

Switch port address identifiers are selected using an automatic

address assignment protocol. All ports within a fabric are assigned

address identifiers. Each individual switch maintains its own address

pool for ports within the switch.

Hardware frame

routing The switch implements hardware routing of frames between

communicating ports and supports self-routing of frames between

communicating ports. The path selection in a multiswitch

configuration is based on a self-routing protocol.

User-defined

routing The switch allows the configuration of user defined routes. Failed

paths are still used in the event of a failure.

Translative mode Translates 8-bit private loop addresses to 24-bit Phantom Public

Addresses to allow fabric-aware devices to access to private devices.

SAN Switch 8 Technical Features

continued

Feature Description

Management The switch can be managed through Telnet, the SNMP agent, or Web

Management Tools included in the StorageWorks Command Console

software. These items are accessible from the Internet Protocol over

the RJ-45 10/100BaseT Ethernet port or any Fibre Channel port. You

can use any SNMP-based management product to access the SNMP

agent and any supported Web browser to use the Java Web

Management Tools.

Name Server The Name Server feature is based on the Simple Name Server model

defined in the Fibre Channel Standard. This function allows external

devices to discover other fabric-connected devices. Name Server

manages a database that relates external device quantities, including

mappings between N/NL_Port 24-bit Fibre Channel physical

addresses, World Wide Names, IP addresses, FC-4 device types, and

Initial Process Associators. External devices can register and query

this information using the Name Server function, which is distributed

across switches in a fabric.

Performance

A minimum aggregate routing capacity of 4,000,000 frames per second is

specified for Class 2, Class 3, and Class F frames. Non-blocking throughput of

up to 8 x 100 MB/s (0.8 GB/s) is provided.

A maximum switch latency of less than two microseconds is specified for

Class 2, Class 3, and Class F frames when the output port is free.

Manageability

The SAN Switch 8 can be managed in-band by using Fibre Channel protocol,

or out-of-band by connecting to the 10/100BaseT Ethernet port. Management

interfaces include Telnet, SNMP, or Web Management Tools.

GBIC Modules

The SAN Switch 8 accommodates up to eight GBIC modules. All interfaces

have status lights on the front panel for quick, visual checks of the

GBIC modules’ status and activity. If your installation requires less than eight

GBIC modules, a metal spring-loaded door protects the unused port positions.

Shortwave (GBIC-SW) and longwave (GBIC-LW) GBIC modules are

supported. The following figure shows a GBIC module.

Figure 1-3. Giga Bit Interface Converter (GBIC) module

GBIC-SW Module

The GBIC-SW module with the subscriber connector (SC) color-coded black

is based on short wavelength lasers supporting 1.0625 GB/s link speeds. The

GBIC-SW module supports 50-micron multi-mode fiber optic cables in

lengths up to 500 meters. The GBIC-SW module uses a Class 1 laser, which

complies with the 21 CFR, subpart (J) standard as of the date of manufacture.

The GBIC-SW module is shipped with a protective plug that should remain in

place when no fiber optic cable is connected to the port.
